Christopher Clark's vision is to bring low-tech solar power to the developing world. The founder of Sunflower Solutions says the idea sprouted from a project involving Miami University engineering students who were charged with developing a business plan for a human-powered well pump. Clark thought there must be a better way. The result is EmPower, Sunflower Solutions' staple: a low-tech, lightweight solar device that follows the sun's rays to obtain optimal energy. The system is simple -- there are no motors or microprocessors. To operate, there are a series of simple color-coded instructions. The system has already been shipped to places like Rwanda and Kenya. This summer, Sunflower will power a hospital in earthquake-ravaged Haiti. Thirty-five people now work for the company, and there are plans to grow.
